On a mission to make musicality as common as literacy

At Yousician, you’ll help shape the future of music education and profoundly impact the lives of millions of people.

Yousician impacts and enriches the lives of millions of people by empowering them to play music they love, learn something new, and nourish their well‑being. We merge music and tech to amplify the everyday. We reimagine the way people learn to play so that everyone can play.

And, you don't need to be a musician to join Yousician!

We’re a band of passionate professionals who love what they do, are great at it, and move to the beat of the same drum. We’re for all players: from newbies to seasoned pros. If you are looking for a rewarding career opportunity that helps shape the future of music‑tech, you’re in the right place!

We’re looking for Web App Developers to help us raise the standard for mobile web. In this role, you’ll create mobile‑first web apps that feel as smooth, fast, and engaging. Web apps that people love to use on their phones, not just a fallback for a native app.

You’ll have the chance to push the boundaries of web technology, build resilient apps that perform even in less‑than‑ideal network conditions, on many types of phones, and help millions of users learn and play music in a way that feels intuitive, inspiring, and joyful.

If you thrive on building performant web apps, shaping user experiences, and moving fast in a multidisciplinary team, this is your chance to make a global impact.

• Contribute to a high‑quality culture through automated testing and knowledge sharing.

• Solid understanding of mobile‑first design principles, caching, and runtime performance optimization. Familiarity with automated testing (unit, integration, end-to‑end).
• Collaborative, curious, and passionate about raising the bar for mobile web.
• Experience with Progressive Web Apps (PWAs) or hybrid development.
• Knowledge of accessibility standards and inclusive design.

• You’ll have an opportunity to join our international team, backed by the top VC’s and competing with the best education applications in the world.
• You’ll have a meaningful and profound impact on the lives of millions of musicians and future musicians all around the world.
• You’ll get to work with a passionate and friendly growing band of PMs, designers, developers and data scientists.
• You’ll receive a competitive compensation package – salary, perks – and work in an awesome office in the heart of Berlin.
• Benefits for lunch, exercise and culture, commuter benefit, free snacks and drinks, medical services, extended insurance, computers, phones.
• Your own instrument – we have a double bass, electric and acoustic guitars, a baby grand piano, digital pianos, mixers, microphones, drums, etc. We have jamming sessions after work on Fridays.
• A recording studio – we have our own recording studio which you are free to use for your own projects.
